Solenoid valve testing status:
Which solenoid valve quality is good? Which solenoid valve quality is poor? What is the norm? What is a test method? At present, the domestic solenoid valve reliability measurement is mostly limited to life, switch function and waveform lack of whole process monitoring, but also need the user's perception and response to judge the reliability of the solenoid valve. Solenoid valve reliability testing system: automatic life testing, waveform monitoring, fully functional data recording, network data query, low cost.
Solenoid valve assembly spiral tube reliability test standards: through the solenoid valve online thermal test and cycle test, real-time record process data, accurately predict the service life of the solenoid valve, analysis of the pilot solenoid valve process data, improve the design and production process, so that the solenoid valve to meet the requirements of high quality. Its advantages lie in: functional test adopts thermal measurement; Big data; High cost performance; Analyze the cause of failure and improve the quality of solenoid valve; Calculate life count, high pressure solenoid valve shortens test cycle.
Principle of thin film solenoid valve: when energized, electromagnetic coil produces electromagnetic force, so that the closed parts leave the seat, open the valve; When the power is cut off, the electromagnetic force disappears and the spring holds down the closing part, making the valve close.
The membrane solenoid valve has a sealed chamber with through holes in different positions, each leading to a different tubing, with a valve in the middle and two electromagnets on either side of the valve. Which side of the solenoid valve is energized, the valve body will be attracted to which side, by controlling the movement of the valve body, different discharge holes will be blocked or leakage. The oil inlet hole is often open, so the hydraulic oil goes into the different exhaust pipes, and the oil pressure pushes the piston, which pushes the piston rod and the piston rod. Mechanical motion can be controlled by an electric current from an electromagnet.
